What causes a bearing to fail?

The majority of bearing failures occur because of improper lubrication. Lubrication failure can occur if the wrong lubricant is used, if not enough lubricant is applied, or if the bearing has been exposed to excessive temperatures that have caused the lubricant to degrade. Corrosion & Contamination.

Can bad alignment cause wheel bearing damage?

But sometimes they break or wear out, like any other part on a car. When that happens, it’s easy to wonder what went wrong. There are three common causes of bearing failure: impacts, contamination, or improper alignment.
